The invention relates to a process for printing cellulose textile fibre material or cellulose/polyester mixed textile fibre material, characterised in that the fibre material is treated with a printing paste or printing ink containing a disperse dye of the formula whereinR-Rare each independently of the other hydrogen, halogen, C-C-alkyl or C-C-alkoxy,Rdenotes hydrogen, C-C-alkyl or a group of the formula &#x2014;SO&#x2014;NRR,wherein Rand Reach independently of the other denote hydrogen,C-C-alkyl which is unsubstituted or substituted by hydroxy, halogen, C-C-alkoxy or C-Caryl, orC-Caralkyl which is unsubstituted or substituted by hydroxy, C-Calkyl, C-Calkoxy or halogen,Rrepresents hydrogen, C-C-alkyl or a radical of the formula wherein R-Rare as defined above.

Process for printing cellulose containing textile fibre material

The present invention relates to an azo dye of formulawherein D is the radical of a diazo component of the benzene, naphthalene, diphenyl, thiophene, benzothiazole, benzisothiazole, thiadiazole, indazole, benzotriazole, pyrazole, anthraquinone, naphthalic acid imide, chromone, phthalimide or diphenylene oxide series, Ris an unsubstituted or substituted aryl radical and Ris an unsubstituted or substituted aryl radical, with the exception of the compounds of formulae (1a) and (1b)to a process for its preparation and to its use in a process for the production of mass-colored plastics or polymeric color particles, and in the dyeing or printing of semi-synthetic or synthetic hydrophobic fiber materials.

Azo dyes, a process for their preparation and their use in the production of colored plastics or polymeric color particles, and in the dyeing or printing of hydrophobic fiber materials

Mixtures comprising a compound of the formula ##STR1## and a compound of the formula ##STR2## in which K is the radical of a coupling component, s is the same in the compounds of formulae (16a) and (16b) and is the number 1 or 2, R and R' are each hydrogen, sulfo, hydroxyl, C.sub.1 -C.sub.4 alkoxy, halogen or cyano, A is C.sub.1 -C.sub.6 alkylene which is optionally substituted by halogen, hydroxyl, sulfato, carboxyl, cyano, C.sub.2 -C.sub.4 alkanoyloxy, C.sub.1 -C.sub.4 alkoxycarbonyl or carbamoyl or interrupted by a group --O-- or --NR'--, or is C.sub.1 -C.sub.6 alkylenephenylene which is unsubstituted or substituted in the phenyl part by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen or sulfo, and R' is hydrogen or C.sub.1 -C.sub.4 alkyl, and the ratio of the compounds of formulae (16a) and (16b) is about 1:1, are suitable as fibre-reactive dyes for dyeing or printing widely varying fibre materials.

Mixtures of fibre-reactive ring-opened phthalimidylazo dyes

Compounds of the formula ##STR1## in which the variables are as defined in the claims and which are suitable diazo components for the synthesis of fibre-reactive dyes are described.

Intermediates for reactive dyes

Compounds of the formula ##STR1## in which the variables are as defined in the claims, which are suitable as fibre-reactive dyes for dyeing or printing widely varying fibre materials, are described.

Fiber reactive phthalimidylazo dyes and use thereof

Reactive dyes of the formula ##STR1## in which D, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as defined in claim 1, are particularly suitable for dyeing or printing cellulosic fiber materials or naturally occurring or synthetic polyamide fiber materials with a high tinctorial yield, and produce dyeings and prints having good fastness properties.
